*WiFi AMPDU TX BA window size*

Type: ``int``

Help
====

.. code-block:: none

    Set the size of WiFi Block Ack TX window. Generally a bigger value means
    higher throughput but more memory. Most of time we should NOT change the
    default value unless special reason, e.g. test the maximum
    UDP TX throughput with iperf etc. For iperf test in shieldbox,
    the recommended value is 9~12.
